^ I don't think it makes a lot of sense for that to be it. That would mean they expected it to never play into anything despite it being a very widely known factor. Letting her participate in two major auditions (Morning Musume and S/mileage) and join a major training program that they eventually had to pay for just wouldn't add up with that being the reason. I don't think we need to know what the actual reason was anyway though, I think as fans we know enough right now.
